Application filed July 30,1902.

To all whom it may concern-.-

Be it known that I, GEORGE EULARKn, a citizen of the United States,residing at Fenton, in the county of Genesee, State of Michigan, haveinvented certain new and useful Improvements in Oil-Cups for Engines;and I do declare the following to be a full, clear, and exactdescription of theinvention, such, as will enable others skilled in theart towhich it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

This invention relates to an oil-cup for .explosive-engines; and itconsists in the construction and arrangement of parts hereinafter fullyset forth.

The object of the invention is to provide simple and efficient means forheating theoil in the oil-cup, so as to render it sufficiently fluid toreadily feed into the cylinder even in extremely cold weather,th'erebyinsuringper- .fect lubrication of the piston under allconditions'.

The above object is attained by the association and arrangement of partsillustrated in the accompanying drawings, in which- Figure 1 is anelevation of my improved oil-cup, showing its connection with thewater-pipe leading'from the jacket of the cylinder audits means for.connection with the cylinder. Fig. 2 is a vertical section therethrough.Fig. 3 is a horizontal section as on line 3 3 of Fig. 2. Fig. 4 is aview, partly in section, showingthe oil-cu p connected with the cylinderand with the water-pipe which water-space around the cyl-.

leads from the inder. A

In many instances where explosive-engines are used for stationary workthey are located in an exposed position, so that in cold weather it isdifficult to keep the oil sufficiently fluid to cause it to flow readilyinto the cylindera condition which sometimes results in the enginerunningdry.

By means of my improved oil-cup I am enabled at all times tomaintain theoil at such a temperatureas to insure a perfect feeding thereof into thecylinder under all conditions of temperature.

Referring to the characters-of reference, 1

Serial No. 117,645. (No model.)

designates an oblong coupling having ihreaded apertures at its ends inwhich may be screwed the water-pipe 2, leading from the water-space 3,which surrounds the cylinder e, the water being kept in constant motionthrough said space and the pipe 2 by a pump or other suitable meansinotshown) for the purpose of keeping down the temperature of the cylinder,as is well understood in the art. Within the coupling 1 is a centralcore 5, having an oil-chamber 6 therein. Passing on either side ofisaidcore is a channel 7, which communicates with the pipe 2 at opposite endsof the coupling andestablishes a passage-way for the flow of waterthrough said coupling around said core. lilounted upon the upper face ofthe coupling 1 is a glass oil-cup 8, which is preferably cylindrical inform and which is closed by a cap 9, having interposed between it andthe upper edge of the cup a gasket 10; The lower end of the cup isseated in an annular recess and rests upon the asher or gasket 11.

Depending f-w'in the cap 9 is a central tube 12, which extendsdownwardly through the cup and oil--chamber and is screwed at its lowerend into'a threaded opening at the hot-.

tom of said chamber. Formed in the wall of the tube 12 near its lowerend is an oil-port 13, through which the oil passes from the chamber 6into said tube. Screwed into" a tapped-opening in the under side of thecoupling 1 and in vertical alinement with the tube 12 is a hollow nipple14; through which the oil is adapted to flew; Passing downwardly throughthe tube 12 and into the nip ple lat is a needle-point valve 15, thestem 16 of which is threaded in the cap 9,,so as to enable said valve tobe adjusted to regulate the flow of oil through the nipple 1% byincreasing or decreasing the distance between the point'of said valveand its seat 17 within said nipple. After adjustment the valve may besecured by the" lock-nut 18.

Below the nipple 14 is a sight-feed glass 19,

' through which the oil is adapted to pass and.

which is held in place by asurroundi'ug an,- nular casing 20, whoseupper end is threaded to screw onto the threaded flange 21 of'thenipple, the upper end of said glass bearing against the washer 22 andthe lower end resting upon the Washer'23, whereby theglass is securelyheld in place and a' tight joint is made between its ends and theconnected parts. The lower end of the casing is provided with a threadedstem 24:, adapted to screw into the c linder, as'shown in' Fig, 3,

' and through sai stemis an oil-discharge passage-way 2a, whichcommunicates with-the port 26, leading into the cylinder. Formed in thecasing 21 is a side opening27, through i which the; glass 19 may be-seen, enabling the engineer to note the feed of the oil as it dropsfromthe nipple ,14. l I l it will be understood that the passage ofthewater from the cylinder through-the coupling 1 will heat the-oil toa. high state of (fluidity, enabling it to ,freely pass from the oil;cup through the nipple 15 and into thecyl- -inder.' As there isacontilnuous flow of this' 1., ,In an oil-cup,-the combination of acoupling having an oil-chamber therein, a water passage-way around saidchamber, an-oil-receptac'le mounted on the coupiingo'ver. saidchamberand communicating therewith, a tube passing through thereceptacle and chamber having an opening which communisates with theoil-chambena valve in said tube to regulate the flow of oil, and apipeadapted to connect said water passage-Way in said coupling with thewater-space around the cylinder of an engine.

- 2. Ina device for the purpose set forth, the combination of a pipe communicatihg with the water-space of acylinder', a coupling in said pipehaving an oi l-chamber, and a. wator-space surrounding sa d chamber,through which water isadapted t flow, and with the opposite ends'ofwhich said pipe isconnec'ted, an oil passage-Way connecting theoilchamber'in said coupling with the interior of said cylinder, asight-feed glass in said pasrsage-way interposed between the couplingand cylinder,- and a valve controlling the communicating oil-passagebetween said cylinder and chamber.

3. The combination of a pipe adapted to communicate with the water-spaceof an explosive-engine cylinder, a coupling in said pipe having anoil-chamber therein around which the water is adapted to flow, anoil-re-- ceptacle mou nted upon the coupling and com- Imunicatingwithsai'd oil-chamber, means connecting the oil-chamber ofsaid couplingwith the interior of said cylinder, anipple through which the oil isadapted to be discharged,

and means. for controlling the flow ofoil throughsaid nippl e. 1

4C. The, combination of a coupli'ng having an foil-chamber therein andpassage for water around said chamber, an oil-cup mounted onthe couplingabove-said chamber, a cap closing saidcup, atube depending fromsaid capand screwinginto an aperture at the bottom of said oil-chamber, anoil-opening in the side of said tube, a nipple screwing into the underface of said coupling in alinemenfiwith said tube, a sight-feed glassaround said nipple,'acasing'holding said glass in place and establishingcommunication between the nip-. pie and the interior or the cylinder,and a needle-valve passing through said'tube arid seating in saidnipple.

In testimony whereof I sign this specifics tion in the presence of twowitnesses.
